I have tanglefoot on all my tree trunks, so I'm hoping that will cut down on re-infestation if I can get the foliage clear. 

I've never used spinosad.  I see various miticides recommended for spider mites but I don't know if I can obtain them on my own.  Have you used this before?

How long do these take to fruit from seed?  I have a seedling in my greenhouse.

2578
Between the tree nails, the dog poop bonemeal fert, and the geodesic greenhouse, I’m worried you are overcomplicating things.

2579
Ive never heard of using iron or steel directly like this, always some kind of chelated iron powder as drench or foliar spray

If it were me I'd keep waiting.  Think about how much fruit you will get when it finally flowers :)

I have a "dwarf" in-ground japanese plum that grows and grows and grows, setting thousands of flowers but the fruit always drops before it is pea sized.  The trunk is at least 6in diameter.  I call it the selfish tree.

I grew a few cherimoya seedlings from grocery store fruit seeds.  They started out great then one died and the other has had stunted wilted leaves for months now but looks like it will recover.  They might just be finicky, my other container trees are fine in the same soil and environment, and I just got a grafted cherimoya that is looking happy.

Is your canistel from seed?  I just ordered a grafted one at at 2ft tall it came with a couple immature fruits already on it

It's a Bruce.

Sometimes seedlings are listed as the parent variety even if they don't come true to seed.  I am growing a few sapote from seed solely to see how they handle my greenhouse environment.  If they thrive I'll ditch them for grafted varieties.

The picture of the trunk is too blurry for me to tell, but check for a graft line.  Im not sure if oranges grow from cuttings easily.  If it is grown from seed it will take forever to flower/fruit

Just sprayed them as the sun was going down, will try to keep it up for the rest of the week

It looks healthy to me.  Is this a seedling?  Or grafted?

What is the round cylinder around the base of the trunk? 

2586
Thats a really nice looking little tree.

Here's an old one in a pot I see at a NJ nursery.

Awesome orchard, Brad.  I especially like the dragon fruit "trees".  I'm shocked how fast they grow (for a cactus).

And thanks for the help with the misting system.

FYI - There's a dedicated citrus forum on this site where others may have more experience.

If the damage to your trees is from spider mites, as bad as your leaves look, you should see some spider mite webbing. Fogging the greenhouse will raise the humidity to a level that will eliminate any mite problems, and make life comfortable for your trees.

I definitely have spider mite webbing on the affected areas.  I had just sprayed them off with the hose before taking those pictures.  I've been doing this every few days but I think I need to be more persistent.

2592
I've read that foliar feeding iron doesn't work for citrus, though the explanation for why doesn't make sense to me... "citrus does not translocate iron well" was the gist of it.  I don't see why it would need to move if sprayed directly on leaves.  I have chelated iron I can add to the soil which I understand is effective.


Today a breaker tripped in my greenhouse had no power for a half hour or so, and temps reached 130F!  Unfortunately I can't tell what tripped the breaker so I don't know if it will happen again.  Plants looked fine when I switched the breaker back on, few had leaves a bit curled but I think they'll be okay.

2593
CCS is very.. sneaky.  They thrive on the underside of leaves and the least accesible areas to spray

2594
I see spider mite webbing and spray it off every day or two, but much like the cottony cushion scale they come back with a vengeance

2595
Im going to assume it is just the spider mites, then.  My trees have been in ground there for months.  Id still like to be able to keep it reasonably cool, though.  Ill see how effective it is soon

2596
I just got my fog pump working today.  I discovered two of the fog nozzles are leaking badly so I need to get replacements, and maybe another thermostat.  Hopefully the fogger will keep temps reasonable but them I will see if I have problems with hard water damaging plants.  My TDS meter says 190ppm for my water supply. 

Might try shade cloth also/instead.  Still figuring this out.  Do you think this damage could actually be sun burn?  I always assumed sunburn was due to intense UV+heat.  The polycarbonate filters all UV, and maybe 20% light when you include angles, greenhouse frame, etc.   My outdoor trees seem perfectly happy in direct sun 10hrs a day, though outdoor air temps are 80-90F while greenhouse is 100-110F.

I could also run my fans faster, they get loud though.

2597
I have hort oil but I’m really worried about cooking my plants as it is sunny this week and its over 100F in my greenhouse when the sun is out.  How long after spraying dilited hort oil are plants considered back to normal in terms of heat tolerance?

2598
Im going to try spraying them more aggressively.  I was reading about spider mites last night and saw that they do not tolerate high humidity, so simple water makes sense.  Also it seems they tend to decline on their own by mid summer, though i dont know how that schedule applies to a northern greenhouse.  All the research reports are from citrus growing states.

2599
Pretty much all of the new growth on the affected trees.  It gets hot in my greenhouse, BUT all the trees I have sitting outside in unfiltered look fine. 

Im looking at spider mite leaf damage photos and the fine specking looks just like recent damage ive seen.  I wonder if the mites have been active a lot longer than i realized and i didnt notice until webbing appeared?

Citrus General Discussion / new growth flushes turning yellow/white
« on: June 23, 2019, 09:09:34 PM »
Recently all my in-ground in-greenhouse citrus had large growth flushes.  The new growth is looking very yellow/white now.  It seems to match up with spider mites, the trees that haven't had much spider mite activity are still nice and green, but the ones with the most spider mites are most affected.  Are spider mites the likely cause, here?  Or is this more likely a nutrient deficiency? 

I just did a ph test and soil is ~6-7ph.  I added a handful of osmocote to each tree a few weeks ago.  Soil doesn't seem wet, at least in the top inch or two I could dig my finger into. 

All my container-grown trees outside are unaffected. 

Here's the Flame grapefruit (I think):


And the Moro has some really bad areas like this:



Even the Valentine Pummelo that Millet sent me is affected, and it is on flying dragon.  The rest either I don't know the rootstocks, or they are some non-optimal ones like C35
